7 Claims.

The present invention relates to such cigar machines, in which bunches are treated in a wrapping device, whereby a finished product is obtained. In such machines there is generally a cutting device for Wrappers, which latter are to be used for the manufacture of said finished product. It also often occurs that the bunch producing device is arranged in proximity to the cigar machine or even that a device for treat- 0 ing the bunches, that is, a buncher, is combined with the rest of the cigar machine.

Two operators are needed for the attendance of .such a machine, whereas one of them handles the bunching and the other manufactures the finished cigars, that is, puts tobacco leaves on a wrapper cutting device, the wrappers then being automatically transported to a wrapping device, where the bunches, which are fed forward from the buncher, are provided with such wrappers. The finished cigar isthen automatically transferred to a place, where it is collected by the one operator, who executes the wrapping operation. In the meantime, the operator exeouting the bunching is occupied With the putting of bunches into the moulds, in which said bunches are pressed and formed, before they are transferred to the wrapping mechanism.

It may occur that the operator who executes thewrapping, that is, puts tobacco leaves on the cutting device, is delayed in her work, because a great part of the tobacco leaves to be cut are defective and consequently after having been placed on the cutting device, where the defects are most easily observed, have to be exchanged for new ones, while the bunches because of a very simple shape can very easily be placed in the pressing moulds intended for them. The result will evidently be that While the operator at the wrapping device will find it difficult to have time to collect the finished product, the operator at the buncher cannot give her full capacity of work. On the other hand, should it happen that the bunches have an especially peculiar shape the placing of said bunches in the molds will be considerably more diflicult, and if at the same time all or almost all the wrappers are correct, the work of the operator occupied at the wrapping mechanism will evidently be facilitated. The work of the other operator will at the same time be more difiicult, and the capacity of work of the operator at the wrapping and cutting device cannot be fully used.

This disadvantage is eliminated by the present invention. The invention is principally char- 1931, Serial No. 572,154

acterized by the fact that the finished product that has not been picked up at the primary, that is, the hitherto usual receiving place, is transferred to a second receiving place, where it is collected.

A preferred embodiment of the invention is shown in the accompanying'drawings.

Fig. 1 shows a vertical side elevation of a device according to the invention and intended for the method according to the invention.

Fig. 2 shows a horizontal plan view of the same device.

Fig. 3 shows a vertical end elevation of the proper wrapping and bunching machine seen from the right side in Figs, 1 and 2.

Fig. 4 shows a detail of the device in a larger scale.

On a frame 1 is arranged a bunch producing device 2 diagrammatically shown in the drawings, as the constructive development of the same forms no part of the invention. The tobacco, of which the bunches are produced is taken from a container 3. The wrapping machine is arranged on a frame 4 and consists among other things of a buncher consisting of two rollers 5 and 6 provided with moulds, the shape of which is corresponding to the shape of the finished cigar. The rollers are arranged to rotate intermittently.

A plunger '7 is arranged to project in the roller 5 through notches .8 into a mould 9, which for the moment is in front of a mould 10 in the roller 6. Another plunger 11 is arranged vertically in the roller 6 in such a manner that it can as the plunger 7 project through notches 12 and the mould 13, which for the moment is at the top of the roller 6. For that purpose the plunger 11 is actuated by an excentric disc 14 fixed on a rotating shaft 15, whereby the plunger is imparted vertical reciprocating movements. The plunger '7 is actuated in the same way as the plunger 11 to make horizontal reciprocating movements. i

An arm 16 is arranged to swing together with a shaft 17 connected to a mechanism, which imparts to the shaft reciprocating swinging movements. This mechanism is not shown in the drawings, as its constructive development forms no part of the invention. The arm 16 is provided with double grippers'18 and 19. On the frame 4 is further arranged a wrapping mechanism 20, which is only shown diagrammatically, as its constructive development forms no part of the invention. Near the wrapping mechanism 20 is a cutting device '21 of known design arranged. An arm 22 provided with a leaf carrier 23 is connected to a shaft 24, driven intermittently from any suitable power source, so that the arm can swing the leaf carrier to and fro between the cutting device 21 and the wrapping device 20.

On a bracket are journaled in bearings 25 and 26 shafts 27 and 28 with a driving roller 29 and an idle roller 30, over which runs a belt 31. The shaft 27 is provided with a chain wheel 32, over which runs a chain 33, which is driven by a pinion 3 1, fixed on a shaft 35, which is coupled by means of a gear to a suitable driving motor 36. A cup 37 is arranged at the end of the belt 31 near the buncher. Therollers29 and 30 rotate clockwise. The place for the operator handling the buncher is numbered 38 and the place for the operator executing the cutting of tobacco leaves for producing wrappers is numbered 39.

The embodiment of the device now described according to the invention works and is attended in the following manner:

When a bunch is produced at the bunch producing device 2 it is inserted by the operator placed at 38 in a moulded at the top of roller 5. During the intermittent rotation of said roller, the bunch finally reaches the position 9 shown in Fig. 4 just in front of the plunger 7, which pushes the bunch out from its mould 9, so that it is brought to and pressed into the mould 10 in the roller 6 just in front of the plunger. During this transferring of the bunch, rollers 5 and 6 are at a standstill. The bunch follows the stepwise rotation of the roller 6 and finally attains the position, which is marked by 13 in Figs. 2 1. When the rollers for a short moment are at a standstill, the plunger 11 projects through the mould 13 and lifts the bunch to the position, shown in Fig. 4. In the meantime, the arm 16 swings from the wrapping device 20 against the plunger 11, and when the latter is in its upper position, the gripper 18 seizesithe bunch and the plunger 11 descends again. The arm swings further over the mould 13 to deliver a finished cigar, held by the'gripper 19. The arm then returns and swings with the bunchyto the wrappingv device 20, where said bunch is delivered.

'In the meantime, the operator placed at 39 has chosen a tobacco leaf from a pack of such leaves and, placed it on the cutting device 21, where a wrapper is cut out. .This wrapper is then taken by the leaf carrier 23 which following the swinging movement of the arm 22 isbrought to thewrapping device 20. ,Here the wrapper is automatically rolled around the bunch, and a finished cigar is obtained.

When the wrapping is finished the grippers 18 and 19 on the .arm 16 approach the wrapping device again. The gripper 19 seizes the finished cigar, and a bunch brought forward from the roller6 by the gripper 18 is then dropped at the wrapping device..- Thereafter the arm 16 swings once more away from the wrapping. device pass,- ing the mould 13 to the belt 31, above which thegripper l9 drops the cigar'near the'driving roller29; which rotates in such a direction that ,the'upperipart of said belt moves against the cup 3'7. If thereis sufiicient time for it, the dropped cigar is immediately picked up by the operator at 39 and placed in a container or possi-bly --'on another transport arrangement, leadingto another receivingplace. J. However, if saidoperator because of the aforesaid reasons has not time to collect the cigars, the latter follow the upper part of the belt 31 to the cup 37 (as shown in Fig. 2), from where it can be picked up by the operator at 38, who in this case has plenty of time at her disposal, as she must regulate the speed of her work after that of the operator at 39. The cigars taken from the cup 37 can then either be stored in cases or boxes, or be brought by means of a convenient transporting device to another receiving place. This is implied as well in this case as at the primary receiving place, also if the expression collect is used. Due to the working conditions it may happen that all or part of the finished cigars are collected already by the operator at 39, or it may happen that the entire finished product is transported to the second receiving place.

I do not wish to limit my invention to the above mentioned details of construction as there are several other embodiments within the scope of the invention. The belt can thus be replaced by any other transport arrangement, and the belt or any other transport arrangement may be driven intermittently and, if this is considered suitable, the transport arrangement may be handled manually. The different and separately known parts of the cigar manufacturing machine, as buncher, pressing rollers, wrapper, cutting device and the transporting devices for bunches and wrappers, etc. can be developed in any way, as their construction forms no part of the invention.
